I recommend moving the wing forward until inverted flight requires no elevator input. This will also improve pitch sensitivity. Rite now you are too short coupled. CG can be as much as 1" aft-spar.

OK, I moved the wing forward about 1/2 inch. Now, it inverts & stays level trimmed. In normal flight when I throttle off, it noses up until it slows then noses down. A friend says I need down thrust (engine pointed downward). What do you think?

Thanks for building one of the best kits I have ever put together! The work you did made my work so much easier. Attached are a couple of pics of my finished SSX. It's built with lights to fly at night.

Maiden flight part 2, happened last night at dusk. Once trimmed, she flew very nice. super soft landings. Had to add a lot of up trim. I think my P11 balsa replacement has the wing incidence off. James, I need a replacement for P11 or the right measurements to cut a new one.

No, I just moved. Regrettably, I decided to skip Perry and SEFF this year. Just not enough time to get my shop put back together and prepare for the two events. I am going to shoot for the fall events.

Hi all,
Maiden flight of my SSX yesterday was wonderful! I don't have pics as of yet. For one, I was by myself, and two, I'm not very proud of my covering job. My first time at it and it didn't quite come out as planned. But that can be changed as I'm sure a crash will be future so when repairs are needed, I can update the covering.

She flew OK but I needed a lot of up elevator to fly level, even though she is balanced about 1" behind the wing spar. DO you gents think I should let her be a bit tail heavy with the COG for level flight or is there something else maybe going on? Other than that, I have throws dialed down on the ailerons and elevator as I'm a beginner. I still have full rudder throws in play. She was nice and docile and very comfortable to fly, other than needing up elevator as I said.
